The actor revealed that the couple are expecting a baby boy on 'The Late Show with David Letterman'.

Goldblum, 62, and Livingston, 32, got married in November last year in Los Angeles.

"She's three months pregnant. She told me the day before we got married,. It's a boy. We picked out a name, as a matter of fact. If it stays ? this is our current thinking ? (it'll be) Elliott Charlie," said the 'Portlandia' guest star.
